Adjusting the Timing Control   

(Factory set to run for approximately 30 seconds after float ball drops): 

 

Use sketch to guide you and the marking on the end of the knob as a 
guide. Control is located on bottom of Ejector and has the small tube 
coming out of it connecting to the small “Tee” on the top of the Ejector.  

 

Pump stops too soon:

 ¼ Turn Timing Knob right (clockwise) to produce 

a 15 Second Longer Run Time. If you close it completely, pump will not 
shut off.  

 

Pump runs too long:

 ¼ Turn Timing Knob left (counter-clockwise) 

produces a 15 Second Shorter Run Time. If you open it too far, pump may 
run for too short a time to be effective.  

 

If you lose your place

 

and must start over:

 Turn the Timing Knob all 

the way in to the right (clockwise) and then back to the left (counter-clockwise) 1 ¼ Turn. This is the factory setting. 

 

30 - 45 seconds run time after the float drops is a good average 

“rule-of-thumb”. Running it dry will not harm it, but it 

does use water unnecessarily when this happens. 

 

This backup sump pump is to be tested to ensure proper operation at least 3-4 times per year. 
Lift the float by hand and confirm pumping, runtime, and automatic shut-off. Record the date 
after each test. 

Place these instructions back into the plastic bag they came in 

and keep them near the pump.
